RESEARCH

In recent years our research program includes: 1) social behavior of birds and other vertebrates, 2) migratory and foraging behavior of shorebirds, 3) behavioral development (laboratory experiments with the effects of temperature on behavior, morphology and physiology), 4) ecology, nesting, and hibernation behavior of Pine Snakes, 5) fate and effects of heavy metals, 6) risk perceptions, concerns and preparedness for future storms, fish consumption, and effects from storms and 7) risk assessment, including value of ecological resources and protection of human and ecological health on Department of Energy Sites.  Each on-going project will be described briefly below.  All of this research is collaborative with a range of scientists, government agencies and officials, and other stakeholders, as well as a number of graduate and undergraduate students, post-docs, and other volunteers. 

            My academic appointment is jointly with Cell Biology and Neuroscience, and in Ecology, Evolution and Natural Resources.  I am also a member of the Environmental and Occupational Health Sciences Institute, and a faculty member of the School of Public Health. 

  1. Our data on the demography and reproductive success of colonial birds in Barnegat Bay for over 40 years allowed us to examine the effects of invasive species, contaminants, and sea level rise. Only Great Egrets and Great Black-backed Gull have increased, while all other species are decreasing, largely due to competition for safe nesting places, increases in severe storms, and loss of colony sites because of sea level rise. While our major studies are in New Jersey, other work on lizards and Olive Sea Turtles in Costa Rice, Emperor Penguins in Antarctica, Common Terns in Mongolia, Cattle Egrets in Africa, and many other species elsewhere have allowed us to compare how animals avoid predators, obtain sufficient food, and breed successfully.  The studies in Barnegat Bay are on-going, as are those of nesting and hibernating Pine Snakes in the New Jersey Pine Barrens (30 + years, see # 4 below).

            Our data show long-term declines in the number of birds nesting in Barnegat Bay and elsewhere, and that these declines continue, and are due to losses of colony sites (due to sea level rise mainly).  These declines occur in Common Terns (shown below), some gulls, skimmers, and some herons and egrets.  Habitat loss is a result of low-lying salt marsh islands used for nesting becoming inundated because of sea level rise, making them no longer usable.  Competition with the larger Herring Gulls (an invasive species that nested farther north) has resulted in the smaller species being forced to lower elevation places, and their nests were flooded out.

Over the last several decades, the number of islands suitable for nesting has decreased for nearly all the colonially-nesting species.  Species with the greatest loss of habitat are the Laughing Gull and Black Skimmer (see below).  Other islands are lost because of competition with Herring Gulls.  These studies will continue as it is critical to understand what the effects of climate change and sea level rise are on a variety of species, to document changes, and to determine how to modify habitat to allow colonial nesting species to nest successfully.  This work is with Fred Lesser, Michael Gochfeld (Rutgers, Robert Wood Johnson Medical School), and Brian Palestis (Wagner College), in cooperation with NJ Endangered and Nongame Program.

  1. Our current work on Delaware Bay involves examining local movements, habitat use, and long migration routes of Red Knots and other shorebirds, and interactions of people with birds. Our goal is to understand the spatial and temporal habitat needs of shorebirds to allow shorebirds and human activities to flourish.  With the use of light-sensitive geolocators we are demonstrating knots fly thousands of km non-stop between stopover sites.  Sufficient foraging space and prey (Horseshoe Crab eggs) are essential to allow them to nearly double their weight to reach their Arctic breeding grounds.  The on-going threat from overharvesting of Horseshoe Crabs for bait, and use of the intertidal for oyster culture, both require extensive study of habitat use and needs, shorebird body condition, and migration patterns.

While the migration patterns were generally known from banding studies, the use of geolocators has provided data on complete routes (times, locations, continuous flights) between wintering and breeding grounds, including stopover sites.  Our data illustrated that some knots overwinter in the U.S. from Maryland to Florida, and that Delaware Bay is essential to their health and well-being.  By placing geolocators on knots at key wintering, stopover, and breeding locations we are working toward understanding the effect of food availability, human development, human disturbance, anthropogenic factors (horseshoe crab overharvesting, aquaculture), and sea level rise.  One of the key questions is whether the knots can physiologically take on enough weight to migrate these long distances, and still arrive on the breeding grounds with enough reserves to lay eggs and breed successfully. The objective is to increase the populations of Red Knots (on the U.S. threatened species list), while fostering the social and economic development of Delaware Bay and other stopover sites.

Track of one Red Knot fitted with a geolocator at Delaware Bay (red dot # 1), New Jersey.  It went to the Arctic to breed, and then to Bahia Lomas in Argentina (red dot # 2).

In addition we discovered that we could use the geolocators to determine whether birds bred in the Arctic, whether they incubated to term, and whether they likely raised young.  This is important because Red Knots and other shorebirds are very spaced out in the Arctic, and nests are difficult to locate.  Understanding reproductive success, in combination with information on climate change is essential to determining the pressure points for population declines.  This work is in collaboration with Larry Niles (Conserve Wildlife of NJ), Mandy Dey (NJDEP), Ron Porter and others.

Burger 6

Data from geolocators placed on Red Knots under different conditions.  In the Arctic, there is no signal because there is no night and day.  However, when the bird sits to incubate, it shows a dark pattern. 

Our research also includes examining the effect of human disturbance on nesting and foraging birds, and the effect of fisheries (for Horseshoe Crabs) and aquaculture (for Oysters) on shorebirds.  Traditional oyster culture was farther north in the bay, where horseshoe crabs do not breed (and shorebirds normally do not forage).  On-going studies are examining Red Knot and shorebird use of the intertidal (out to 300 m from mean high tide).  Oyster racks are places at least 100 feet from shore. 

Results to date indicate that Red Knots avoid intertidal sections with oyster racks, especially when oystermen work on them.  Further, in another experiment, we found that knots avoided untended racks, but did not avoid sections with artificial reefs or controls (see figure below).  Such studies require many years of replicates to capture the natural variation due to weather constraints, bird variations, and variations in horseshoe crab breeding.

  1. Factors affecting behavioral development in reptiles and birds is investigated in our lab, particularly with respect to birds and Pine Snakes. Laboratory and field experiments with the effects of incubation temperature on Pine Snakes have demonstrated that low incubating temperatures result in behavioral deficits in locomotion, anti-predator behavior, and foraging ability. These deficits result in hatchlings being generally unable to find hibernation sites before onset of cold weather in the fall, decreasing parental fitness.  These low incubation temperatures, subsequently found in other snakes and other reptiles, contribute to determining geographical ranges of reptiles.   Similar studies with turtles in our lab indicated similar behavioral deficits.  This work is in collaboration with Michael Gochfeld, Robert Zappalorti (CEO, Herpetological Associates), and Emile DeVito (Conservation Foundation of NJ).

Poaching is a problem as in some years 40 % of our marked nests were poached by snake collectors.  We are countering high rates of poaching by head-starting hatchlings, obstructing the free access to nesting sites, and working with officers to reduce these effects.  We demonstrated that off-access to key nesting sites can increase productivity and populations.  Further, Pine Snakes require open exposed places within the Pine Barrens, and many of these are succeeding into dense Pine forests.  Continued restoration and management are required to keep nesting sites optimal.  These studies are in conjunction with Michael Gochfeld, Robert Zappalorti, and Emile DeVito, and numerous graduate students.

5.  Our laboratory is conducting long-term biomonitoring of heavy metals in fish, birds, and mammals to assess possible effects on the organisms themselves, and on predators that eat them (including people who consume fish).  These fate and effects studies have focused on lead, mercury, cadmium, chromium and radionuclides.  Lead and cadmium have generally decreased since the early 1970s, but mercury (largely from atmospheric deposition) have not.  Our laboratory experiments have indicated that levels equivalent to the highest exposure gulls obtain in the wild can cause behavioral deficits (cognitive problems), and that these can lead to increased mortality. 

Burger 12

In other laboratory experiments we showed that lead disrupts individual recognition (a cognitive ability).  With time, recognition increases in the controls, but does not for the lead birds and by 20 days of age there is still a significant difference in their ability to recognize their parents (see graph below).  In the wild, this leads to lower survival (young that don’t recognize their parents wander into neighbor’s territories, and are killed).  These, and other laboratory experiments, can be used to develop paradigms for understanding behavior of people.

Burger 13

We have long-term data on heavy metals in birds (and some on fish) from other bays and estuaries from Chesapeake Bay to Boston Harbor.  This work on heavy metals in birds is the longest-running data set on birds in the U.S., involving several species (gulls, terns, skimmers, herons, egrets).  Mercury is a major problem for humans and other biota, particularly in marine and coastal environments.  Mercury causes locomotory and cognitive deficits.  Birds are excellent indicators of contaminants in the environment because they reflect level humans obtain when eating fish, and of the exposure of other predators (Osprey, herons, other species).   We have been monitoring levels in eggs of Common Terns since 1970.  These levels have been analyzed in our lab (and we continue to do so) using the same methods (see below).  It is VERY important to continue these studies at a time when China is adding coal-fired power plants every week, and national regulations concerning mercury from our own power plants are being reduced.

  1. It is essential to understand the risk perceptions and concerns of people about any number of issues that affect the health and well-being of species and ecosystems. Our research in this area has included understanding concerns and perceptions of people about fish consumption (including fishing behavior, consumption patterns, and risk from contaminants in fish, see above), understanding the concerns and perceptions about the value of healthy coastal ecosystems and natural resources, understanding the concerns, perceptions and future preparedness of people following Superstorm Sandy.  These studies are both ecological and responsive to emerging problems (such as Sandy).

            Fish consumption studies in NJ, NJ, Idaho, South Carolina, Georgia, Iowa, Washington and other places (including Singapore) have shown that often people are aware of the risk from contaminants and know about the health                  effects, but not how to balance the risks and benefits.  Mercury is the greatest risk from fish consumption (determined from studies in our lab with a range of fish at different trophic levels), but can be reduced by selecting fish                    low on the trophic, eating a variety of fish species, and limiting portion size.  Further, our laboratory studies have demonstrated the relationship between selenium (protective against mercury) and mercury levels in different fish,                and the relationship between fish size and these levels.

To understand how much, and why people eat contaminated foods, Studies on the levels of radionuclides and heavy metals must be examined, and consumption rates must be determined.  One of our studies in Amchitka Island (in the Bering Sea) examined radionuclide levels in foods consumed by the Aleuts (Native Americans), as well as fish, crabs and other foods eaten by people in the lower 48 states (over half of our fish come from the Bering Sea.  From 1965-1971 the US conducted 3 underground nuclear tests, and contamination in biota, subsistence foods and commercial foods were not examined. This was a CRESP project, and involved Aleuts on the expedition, as well as an expedition on a NOAA fishing trawler.  We have continued the work at other DOE sites (see below).

To build support for the protection of coastal habitats (dunes, beaches, marshes) in natural conditions, it is essential to understand how people view these resources.  People only support (both emotionally, politically, and financially) things that they understand and appreciation.  Over the years we interview people periodically about their attitudes and perceptions of the value of ecological resources (including endangered species, birds, fish, marine mammals, algae).  This allows us to provide managers with information of how these values change over time.    With this background of data, we were able to design and implement a survey of people in both coastal and inland New Jersey following Hurricane Sandy (within 100 days of the storm).  We found that during Sandy, medical issues were the primary concern of shore respondents, while secure and safe food and water were the major concerns for inland NJ residents.  Before the storm many people did not heed warnings and evacuation orders, but were worried about property damage.  After concerns were for health and safety of family and friend

Burger 23

Within 100 days of Sandy, most people did not recognize the importance of soft, ecological barriers to prevent damage in their communities.  Their concerns focused on property damages and inconveniences (see below)

Burger 24

This data base allowed us to conduct a study for CDC on the experiences of patients in Federally-Qualified Health Centers.  It is important to understand the relationship between effects (physical), perceptions of damage, understanding of man’s role, and future preparedness to helping design new preparedness plans for future events.  This information is critical to allow State and Federal Agencies to deal with new hurricanes (such as Harvey, Irma), and to help NJ State managers to be prepared for future storms.  This project is a collaboration with Michael Gochfeld (Rutgers Medical School) and Cliff Lacey (Director of Rutgers Preparedness Center).  Understanding the perceptions, concerns, and effects from severe events such as Superstorm Sandy allow individuals, communities, and governments to better prepare for future events.  

Interestingly, three years after the storm, people were more convinced that storms are due to climate change, they will come more often, and these changes are likely due to human activity.  However, they still did not fully recognize the importance of salt marshes and sand dunes to prevention of flooding.

  1. On-going studies on the Department of Energy sites are aimed at understanding the risk to humans and ecological receptors from radionuclide and chemical contamination (as well as physical disruption). Our work includes studies at Amchitka Island (Aleutians, Bering Sea), Hanford Site (Washington), Idaho National Laboratory, Los Alamos (New Mexico), Brookhaven Laboratory (Long Island), Oak Ridge (Tennessee), and Savannah River Site (South Carolina).  Specific studies include evaluating ecological resources on sites, understanding risk to ecosystems, ways to reduce risk during remediation, preserving these relatively pristine ecosystems (usually < 10 % are industrialized), protecting human health, assessing risk to humans from fish consumption, understanding perceptions about the importance of ecological resources, and fostering stakeholder involvement and consensus.

This work is in collaboration with the Consortium for Risk Evaluation with Stakeholder Participation (CRESP), including David Kosson, Chuck Powers, Michael Gochfeld, and many others, including Native American Tribes and other environmental justice communities.

TRANSLATIONAL SCIENCE AND ENVIRONMENTAL JUSTICE

In Today’s World it is essential to be able to translate science for managers, public policy makers, and the public.  Governments, agencies and people will only protect (and finance) the things they understand, appreciate, and feel are important.  Making science accessible to the public is a key responsibility of researchers.  Our science can be made available through articles in popular journals or on-line blogs, through books designed for the public, public lectures and talks, meetings, and involving the public in the design and implementation of research.  Two other important aspect require mentioning: 1) commitment to always remember and include diversity, and those who are vulnerable, and 2) always include a range of stakeholders in science.

DISCOVERING AND NAMING A NEW SPECIES OF FROG

One of my graduate students (Jeremy Feinberg) and I discovered, and described and named a new frog (with other collaborators) from the New York/New Jersey metropolitan area (truly unexpected).  This involved ecological, acoustic, morphological, distributional, and DNA-laboratory studies.  The new species of Leopard Frog (Rana kauffeldi), called Atlantic Coast Leopard Frog.  This finding, and the associated publications, indicates the importance of interdisciplinary disciplines and universities collaborations in modern-day biology.
